Only using a proxy if that fails on them. This might be of some help identifying the relevant ports etc: http://wiki.squid-cache.org/ConfigExamples/Chat/MsnMessenger Just invert the rules to 'allow' instead of 'deny' for squid.conf. There are possibly other ports such as 443 involved with authentication and their handshaking that need to be accounted for. Google around for the live ports, you may need a firewall log or packet trace to find specific detals if there is any other problems. Amos
